Description
Die Erfindung betrifft einen Stromabnehmer nach dem Oberbegriff des Hauptanspruches, wie er durch die DE-OS 36 10 455067 bekannt ist.The invention relates to a pantograph according to the preamble of Main claim as it is known from DE-OS 36 10 455067.
Die Kontaktfläche eines solchen Stromabnehmers ist ca. 50 mm lang und erfordert eine beachtliche Anpreßkraft, damit die Flächenpressung zum Gewährleisten eines guten Kontaktes und hoher Stromübertragung ausreichend groß ist. Das Aufbringen der Anpreßkraft ist bei großen Krananlagen kein störendes Problem, kann aber bei kleinen, an leichten Schienen fahrenden Katzen zu Störungen durch große Verschiebekräfte führen.The contact surface of such a pantograph is about 50 mm long and requires a considerable contact pressure, so that the surface pressure to Ensuring good contact and high power transmission is sufficiently large. The application of the contact pressure is large Crane systems are not a problem, but can be used for small, light ones Cats on rails cause disruptions due to large displacement forces to lead.
Aufgabe der Erfindung ist es daher, einen Stromabnehmer so zu gestalten, daß bei allen Einsatzfällen eine einwandfreie Strom- oder Informationsübertragung bei geringen Verschiebekräften gewährleistet ist. Diese Aufgabe wird durch die Merkmale im Patentanspruch 1 gelöst.The object of the invention is therefore to design a pantograph so that in all applications a perfect current or Information transfer guaranteed with low displacement forces is. This object is solved by the features in claim 1.
Der Tragkörper mit dem Gleitkontakt ist über den Bolzen nach Art einer Schwinge pendelnd an dem Lagerbock gelagert, der von einer Feder stets zur Schleifleitung hin beaufschlagt wird und die beiden Kontaktflächen dagegen drückt. Die Kontaktflächen selbst sind klein und haben auch bei geringer Federkraft und dem damit verbundenen kleinen Gleitwiderstand eine große Flächenpressung an der Schleifleitung, so daß die Informations- und Stromübertragung auch dann gewährleistet ist, wenn die Oberfläche der Schleifleitung an einer Stelle eine Kontaktstörung hat.The support body with the sliding contact is like a over the bolt Swing arm swinging mounted on the pedestal, which is always by a spring to the conductor line and the two contact surfaces opposes. The contact areas themselves are small and also have low spring force and the associated low sliding resistance a large surface pressure on the conductor rail, so that the Information and power transmission is guaranteed even if the Surface of the conductor rail has a contact fault at one point.
Der Lagerbock ist vorzugsweise über von einer Druck-Feder beaufschlagte Parallelogrammschwingen an dem Anschlußbock angelenkt. Der Tragkörper ist in bekannter Weise mit einem Lagerbolzen in einer Bohrung des Lagerbockes gelagert, so daß sich der Gleitkontakt auch bei unsauber verlegten Schleifleitungen diesen anpassen kann. Der Gleitkontakt ist mit einer Haltenase nach Art einer Schnappverbindung in einer Ausnehmung des Tragkörpers eingesetzt.The bearing block is preferably acted upon by a compression spring Parallelogram swings articulated to the terminal block. Of the Support body is in a known manner with a Bearing pin mounted in a hole in the bearing block so that the sliding contact also applies to dirty conductor lines can adjust. The sliding contact is with a retaining lug in the manner of a snap connection in one Recess of the support body used.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und im Folgenden erläutert.An embodiment of the invention is shown in the drawing and explained below.
Es zeigen:Show it:
Fig. 1 einen Stromabnehmer in der Seitenansicht, teils im Schnitt, Fig. 2 eine Draufsicht auf Fig. 1. Fig. 1 shows a current collector in a side view, partly in section, Fig. 2 is a plan view of Fig. 1.
Der Gleitkontakt 1 hat an beiden Enden im Anschluß an Anlaufschrägen 1c Kontaktflächen 1a und zwischen diesen einen Rücksprung 1b. Der aus Graphit bestehende Gleitkontakt 1 ist mit seinem unteren Bereich in einen aus einem Kunststoff bestehenden Tragkörper 2 seitlich eingebettet und ragt mit einem Kontaktanschluß 1d, an den eine nichtgezeichnete Leitung anschließbar ist, durch den Tragkörper 2. Der Gleitkontakt 1 ist mit einer mit Vorsprüngen 1f versehenen Haltenase 1e nach Art einer Schnappverbindung in einer Ausnehmung 2b des Tragkörpers 2 befestigt.The sliding contact 1 has 1 c contact surfaces 1 a at both ends following run-on slopes and between them a recess 1 b. The graphite sliding contact 1 is embedded laterally with its lower area in a support body 2 made of a plastic and projects through the support body 2 with a contact connection 1 d, to which a line (not shown ) can be connected . The sliding contact 1 is fastened with a retaining lug 1 e provided with projections 1 f in the manner of a snap connection in a recess 2 b of the supporting body 2 .
Dieser ist mit einem Lagerbolzen 2a in einer Bohrung 4a eines Lagerbockes 4 gelagert, der über eine Parallelogrammschwinge 7 mit einem Anschlußbock 6 eines nicht-gezeichneten Stromabnehmerwagens verbunden ist. Zwischen den Armen der Parallelogrammschwinge 7 ist eine Feder 5 in Form einer Druckfeder angeordnet, die an zwei sich überdeckenden Halbrundleisten 9 geführt ist. Die Halbrundleisten 9 sind an den Angriffsbolzen 8 für die Feder 5 angelenkt und führen diese aufgrund ihrer Überdeckung, die sich in der Länge bei Bewegungen der Parallelogrammschwinge 7 ändertThis is mounted with a bearing pin 2 a in a hole 4 a of a bearing block 4 , which is connected via a parallelogram 7 with a terminal block 6 of a pantograph carriage, not shown. A spring 5 in the form of a compression spring is arranged between the arms of the parallelogram rocker arm 7 and is guided on two overlapping semicircular strips 9 . The semicircular strips 9 are articulated on the engagement bolts 8 for the spring 5 and guide them due to their overlap, which changes in length when the parallelogram arm 7 moves
